There are many terms created by modifying or transferring the underlying meaning in current specialized languages, metaphorization being a semantic process at which terminologies are used at all stages of their formation. In the present paper, the metaphorization process in the specialized languages is analyzed, the way in which the meanings of the words evolve in the process of terminology and reorganization of the sports language in Romanian, the conceptual source domains of Romanian sports terms formed by metaphorization were determined and illustrated with concrete examples. As a result of the analysis carried out in the paper, it was found that in the sports language, the terms formed by metaphorization were taken from both the common language (through a terminology process) and from other specialized languages (military, biological, geographic, etc.) , being subjected to the process of re-terminologization. Often, the latter also cross the stage of de-terminologization. Five of the six source domains of conceptual metaphors attested in contemporary Romanian are also found in the specialized sports language: Objects, Plants, Animals, Man, Natural phenomena. There is a trend of predominance of the object-oriented conceptual model and the anthropomorphic one, these categories are the most numerous in the examples chosen by us. The conceptual metaphors of the sports language are based especially on form similarities and those related to the character of movements. The phenomenon can be explained by the fact that most of the metaphor terms are created by association with man's own image and the objects of everyday life, most of which are visual images.
